Account opening

I went to open up accounts for my kids at Capitec and I had all the necessary documents needed. the fore front lady checked them and she advised that I need to have an original letter for the municipal rates. In this day and age where post office is either on a go slow or not working at all we get our letters delivered at home however i have ended up with other peoples letters that I don't even know of because the delivery guy just doesn't care so I opted to get my statements via email, however this was not good enough to them I have an account with them already could they verify on their sustem with what i have already. I do understand that they are trying to avoid any ***** but they need to also understant the situation on an individual basis.
